A bracket installed to secure a high idle component onto the engine throttle arm can hook the wire harness and prevent its return to idle speed.

Consequence Summary

The engine throttle can stick partially open resulting in loss of throttle control and an accident.

Corrective Summary

Dealers will relocate the high idle bracket away from the throttle linkage and secure the wiring harness away from the throttle linkage.
